Toxoplasmic retinochoroiditis is a common cause of posterior uveitis. This study aimed to evaluate the serum concentrations of CC and CXC chemokines in patients with acute toxoplasmic retinochoroiditis.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> The levels of five chemokines (CCL2, CCL11, CXCL9, CXCL8 and CXCL10) were evaluated in the serum of patients with active toxoplasmic retinochoroiditis (<jats:italic>n<\/jats:italic>\u2003=\u200355) and control subjects (<jats:italic>n<\/jats:italic>\u2003=\u200340). In a subset of patients (<jats:italic>n<\/jats:italic>\u2003=\u200318), a second measure of serum levels of chemokines was performed after the completion of oral treatment with pyrimethamine (25\u2003mg\/day), sulphadiazine (1\u2003g, four times per day), folinic acid (7.5\u2003mg\/day) and prednisone (initial dose: 1\u2003mg\/kg\/day) for approximately 30\u2003days.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> Patients with toxoplasmic retinochoroiditis, notably those presenting with vasculitis, had increased serum levels of CXCL8 (mean\u2003\u00b1\u2003standard error of the mean [SEM] 35.1\u2003\u00b1\u20036.5\u2003pg\/ml) compared with control subjects (mean\u2003\u00b1\u2003SEM 16.0\u2003\u00b1\u20032.3\u2003pg\/ml; p\u2003=\u20030.01). There were no differences between patients and controls in serum levels of the other chemokines measured. The size of ocular lesions correlated significantly with serum levels of CXCL8 and CXCL9. After treatment, there was a significant reduction in serum levels of CXCL8. Severity of vitreous opacities did not correlate with serum levels of these chemokines.<\/jats:p><jats:p><jats:bold>Conclusions:\u2002<\/jats:bold> These data suggest a role for CXCL8 in the inflammatory process of acute toxoplasmic retinochoroiditis. Furthermore, CXCL8 may be a useful marker for patient
